SPECIFICATION forming part of .Letters Patent No. 295,005,ldated March 1l, 1884.

Application Bled November 17, 1883. (No model.)

To all whom t may concer/t:

Be it known that I, TIMOTHY HAYES, of Andersons Ferry, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Apparatus for Cooling Mash, Src., of which the following is a specification.

This invention has for its object to' provide novel and efficient devices for cooling mash or wort as it passes from the mash-tub to the fermenting-tank, wherebyaccess may be had to all the parts for the purpose of cleaning or repairing the same.

To such end my invention consists, essentially, in the construction and arrangement of parts hereinafter described and claimed, reference being hadto the accompanying drawings, in which- Figure l is a sectional elevation of my im- ,section of one of the chambers, showing the manner of sinking the bottom plates into the wooden frame. Y

Similar letters of reference indicate similar parts.

A A are a series of wedge-shaped Waterchambers, consisting of frames a a and bottom a a', the shallow ends of which chambers are alternately disposed at the opposite ends of the cooler. All of the chambers A, excepting the lowermost one, are furnished withbottoms of copper or other suitable material; but this chamber has a wooden bottom, a2; likewise, the uppermost chamber A is covered with a wooden cap, a3.

B B are a series of inclined mash-chambers of uniform depth from end to end, placed, as shown in Fig. l, between the wedge-shaped chambers A, and consisting of wooden frames b and copper bottoms b. The bottoms a and b are plain flat plates of copper, rabbeted into the edges of the frames a or b, as clearly shown -in Fig. 3, so that when one chamber, as A, is

pressed rmly down upon another chamber, as B, a mash-tight and water-tight joint is made.

of each frame engage with corresponding holes in the next chamber, A or B, below, to properly locate the chambers in the cooler.

Dowel-pins a4 upon the lower edgesv The several chambers A and B alternate one above the other, and, as shown in Fig. 1, are bound together with vertical tie-bolts D and binders D', which binders are prevented from slipping transversely upon the top a or bottom a2 by the cheek-pieces d d. Cheeks A and B upon the sides of the chambers A and B prevent the chambers from sliding endwise under pressure-of the tie-bolts D, which, owing to the wedge form of chambers A, would happen but for the cheeks A or B taking against the tie-rods. The dowel-pins a4 also assist in preventing end-thrust of the chambers when the cooler is made up and the several chambers bound tightly together by the tie-rods D and binders D.

C is the inlet-pipe for the coolingwater. which passes upward, as shown by the arrows in chamber A, through pipes H, from chamber to chamber, and finally vents at the outlet-pipe E.

F is the inlet-pipe for the hot mash, which ows by gravity in the direction of the arrows in chambers B, through pipes I, from chamber to chamber, to the ve11t-pipe G, whence it passes to the customary fermenting-tubs. It .will be observed from examination of Fig. l that the general course of the hot mash is downward, while the general course of the cooling-watei` is upward, the flow of the hot mash and cooling-water being in opposite directions through the several'chambers A and B. The chambers B are made compara-tively shallow, and both the upper and lower surfaces of the volumes of hot mash are exposed to the cooling inuence of the water in the chambers A. The pipes H and I may be screwed from above into the plates c b, or may be attached to said plates by anges and bolts,

IOO

the generation ot' injurious acids by the impregnating ofthe wood ot' chambers B with the mash, the sides of these may be lined with copper or other suitable material to prevent contact of the mash with the wood.

I am aware that it is not new to arrange a series o1 reversclyineiined chambers ina case and alternately connected at their ends; also, that a box has been divided by parallel partitions to form chambers alternately connected by posts at the ends of the partitions, and a series of parallel pipes arranged in said chambers and alternately connected at their ends, so that beer will flow in one direction through the pipes and in the opposite direction through the chambers. .Huch ieatures,therefore,I disclaim.

Having described claim isl.. In an apparatus for cooling mash in transit from the mash-tub to the ferment-ingtanl, the combination oi' a series of inclined closed chambers,A,for the passage of the cooling agent, a series of inclined. closed chambers, B, for the passage of the mash, said closed chambers alternating one above the other and reversely inclined, the pipes II, alternately connecting the ends of the closed chambers i'or the cooling agent, the pipes I,alternately connecting the ends of the closed chambers 'l'or the mash,the inlet-pipe F, for entrance ofthe mash to the upper inaslrclialnber,the outlet-pipe G, for the discharge ol.' the mash from the iower mash-chamber, and the inlet and outlet pipes C and I), connected, respectively, with the u pper and lower closed chambers for the cooling agent, substantially as described.

2. The combination ot' the series ol' inclined closed chambers A, for the passage of the cooling agent, the inclined closed chambers B, i'or the passage oi the 1nash,alternatel y interposed between the other closed chambers, the bottom wall of one chamber constituting the top wail of the adjacent chamber, the pipes II, alternately connecting the ends of the closed chambers for the cooling agent,the pipes I, alternately connecting the closed chambers l'or my invention, what I the mash, and the pipes F and Il, C and G, connected, respectively, with the uppermost and lowermost closed chamber, substantially as described.

3. The combination of the reversely-inelined chambers A and B, alternately disposed one above the other, and connected alternately at their ends, respectively, by the pipes II and I, for the passage in opposite directions ot' the cooling agent and the mash,the cheek-pieces A and I5 on the side walls ot' the chambers, the vertical tiebolts I) and nuts D', clamping all the' chambers together and engaging the check-pieces,and the respective inlet and outlet pipes C, l", G, and ll, substantially as Shown and described.

Li. The combinationotthc rcversclyinelincd chambers A and l, alternately disposed 011e above the other, the bottom of one chamber constituting the top of the adjacent chamber, and said chambers alternately connected at their ends,respeetivcly,by the pipes Il' and I, i'or the passagein opposite directions of the cooling agent and the mash, the cheelbpieces A and B on the side walls of the chambers,the cheelcpieces d on the top and betteln chamA bers, the comieeting-bolts and nuts clamping the chambers together and engaging the respective cheek-pieces, and the inlet and outlet pipes G and l?, E and G', substantially as described.

5. rIhe combination of the inclined chambcrsA and B, alternately arranged one above the other, and connected as described, and having dowelpins e on the lower edge oi'caeh chamber, engaging the upper edge of the adjacent chamber, with the vertical tic-bolts I) and nuts D, Vfor clamping the chambers one upon the other, substantially as described.

In testimony whereof I have signed my name tothe foregoing specification in thepresenee of two subscribing witnesses.
